Measure the temp, and note when it opens. Then check versus the manual. If it opens too quickly, get a new one....   Bazzle (Bazzle) New Member Username: Bazzle Post Number: 28 Registered: 09-2003 Posted on Monday, October 13, 2003 - 03:17 am:    Just buy a new one and gasket. If faulty sometimes doesnt show in the water test. Tip: when putting in new or old back in use contact adhesive drops to hold in place before putting elbow back on. Many drop down and cause leak during reinstall. bazzle   Bill Howell (Billh13) Member Username: Billh13 Post Number: 214 Registered: 03-2003 Posted on Monday, October 20, 2003 - 11:07 am:    Yah, you got a stuck thermostat. 190 degree F for small block chevy. I pulled my old one out and took it with me to Auto Zone to match it up. Don't worry about the rattle valve it will work fine without one.
